The unique “flavor step” tents are louvered to hold drippings and re-vaporize juices. This 3-Burner Liquid Propane Gas Grill with Folding Side Shelves also acts as a heat deflector to protect the burners. Uses an exclusive cooking system with a Vented Hood Liner that removes smoke from front to back, expelling vapors out the back. It also eliminates blasts of Hot Air when the hood is opened. This cool feature also helps keep the Stainless hood from turning color and lowers the hood touch temperature, by directing the airflow away from the hood, it helps lock in food’s natural juices and reduces cooking time. Separately controlled cooking zones let you grill a succulent filet to perfection while simultaneously cooking mouthwatering shrimp at a lower temperature. The UL certified patented safety tank ring grasps the tank by the collar, making it impossible to dislodge the tank from the grill. The two folding side tables make this grill measure 51.2 in. Wide folded out and 32 in. Folded down.
